| Term | Definition |
|---|---|
| electric charge | a fundamental property that leads to the electromagnetic interactions among particles that make up matter |
| static electricty | electric charges at rest generally produced by friction or induction |
| electric conductor | a material in which charges cannot move freely |
| electrical insulator | a material in which charges can move freely |
| semiconductor | an element or compound that conducts electric current better than an insulator does but not as well as an conductor does |
| electric current | the rate at which electric charges can pass at a given point |
| resistance | in physical science the opposite presented to the current by a material or device |
| voltage | the amount of work to move a unit electric charge between two point expressed in voltages |
| electric circuit | a set of electrical components connected such that they provide one or more complete paths for the movement of charges |
| series circuit | a circuit in which the parts are joined one after another such that the current in each part is the same |
| parallel circuit | a circuit in which the parts are joined in branches such that the voltage across each part is the same |
